How to Dispute Your Medical Bill and Avoid Overpaying for Healthcare (Updated May 2025)

Medical bills can be complicated and difficult to understand, leading to frustration and uncertainty about what you're actually being charged for. Many bills contain errors, duplicate charges, or include unnecessary fees that could cost you thousands.

A recent study published in JAMA Health Forum found that among people who disputed a billing error, almost three-quarters reported that the mistake was corrected. About 62% of people who reached out about an unaffordable bill said they got a payment plan or price drop. This shows that speaking up about medical bills is often worth the effort.

Fortunately, disputing a medical bill is possible with a structured approach. This guide will walk you through the process step by step.

Understanding Your Medical Bill

The first step in disputing a medical bill is understanding it. Go through your bill line by line, paying close attention to each itemized service, insurance adjustment, and co-pay.

Key Insurance Terms to Know:

• Deductible: The amount you pay before insurance starts covering costs.
• Out-of-Pocket Maximum: The maximum amount you'll pay within a year.
• Coinsurance: The percentage of costs you pay after meeting your deductible.
• Copayment: A fixed dollar amount you pay when receiving certain treatments.
• Premium: The amount you pay each month for insurance coverage.

Understanding these terms will help you distinguish between what you owe and what should have been covered by insurance.

Getting an Itemized Bill

Always request an itemized bill with all billing codes listed. A standard bill often shows just a summary of charges, while an itemized bill breaks down every service, medication, and supply you were charged for, along with their corresponding billing codes.

According to patient advocates, hospitals are required to provide an itemized bill within 30 days of your request. This detailed statement is essential for identifying potential errors or overcharges.

Common Billing Errors and How to Spot Them

Billing errors are incredibly common, and spotting them can prevent you from overpaying. Here are some common issues to look out for:

1. Duplicate Charges: Check for repeated charges for the same service on the same day.
2. Unbundling: This occurs when services that should be billed together as a package are split into individual charges, resulting in higher fees.
3. Upcoding: When a provider bills for a more expensive service than what was actually provided.
4. Unrendered Services: Make sure the bill only includes services you actually received.
5. Incorrect Patient Information: Check that your name, insurance information, and billing address are correct.
6. Denied Claims by Mistake: Insurance companies sometimes deny claims due to processing errors, so review your Explanation of Benefits (EOB) carefully.

Identifying these errors can be challenging, but the potential savings can make it well worth the effort. One Solace advocate refuted a $50,000 bill and the patient ended up paying $0 out-of-pocket!

Essential Documentation for Disputing Bills

Having the right documentation is crucial when disputing a medical bill. Gather the following items to strengthen your case:

1. Explanation of Benefits (EOB): This document from your insurance company shows what was covered and any discrepancies.
2. Itemized Bill: An itemized statement from your provider detailing each service or procedure.
3. Insurance Policy Information: This helps clarify your coverage terms and limits.
4. Medical Records: These can verify what treatments you actually received.
5. Communication Records: Keep detailed notes of all conversations, including names, dates, and what was discussed.

Organizing these documents provides a clear overview of what you're being charged and what insurance has covered.

How to Contact Providers and Insurers Effectively

Once you've identified potential errors, it's time to reach out to the correct parties, whether that's your healthcare provider or insurance company.

Who to Contact First:

• For provider billing errors: Start with the billing department of your healthcare provider if the error is on their end.
• For insurance coverage issues: Contact your insurance company if the problem is related to what should have been covered.

Effective Communication Tips:

1. Be polite but firm: Maintain a courteous tone while clearly stating your concerns.
2. Keep records: Document all calls with names, dates, times, and notes about what was discussed.
3. Use written communication: Follow up phone calls with emails or letters to create a paper trail.
4. Be specific and concise: Clearly state the issue, reference specific charges or codes, and explain why you believe there's an error.
5. Request written confirmation: Ask for any agreements or promised corrections in writing.

Filing a Formal Dispute

If your provider or insurer is unresponsive or denies your claim without reason, filing a formal dispute may be necessary.

When to File a Formal Dispute:

• After unsuccessful attempts to resolve the issue through phone calls or emails
• When you receive a denial letter from your insurance company
• If you're being billed for services that should be covered
• If you've identified clear errors that the provider refuses to address

How to File a Formal Dispute:

1. Write a detailed letter: Explain the specific errors or issues with your bill, include your account number, date of service, and what correction you're seeking.
2. Include supporting documents: Attach copies (never originals) of your itemized bill, EOB, and any relevant medical records.
3. Send via certified mail: This provides proof of delivery and when it was received.
4. Request a response by a specific date: Give a reasonable timeframe (typically 30 days).
5. Copy all relevant parties: Send copies to your provider's billing department, your insurance company, and keep one for your records.

Protections Under the No Surprises Act

The No Surprises Act, which went into effect on January 1, 2022, provides significant protections against unexpected medical bills.

Key Protections Include:

• Protection from surprise out-of-network bills for emergency services
• Protection from out-of-network charges at in-network facilities without proper notice
• Requirement for good faith estimates for uninsured or self-pay patients
• Right to dispute bills that exceed estimates by $400 or more

If you receive a bill that violates these protections, you can file a complaint with the Centers for Medicare & Medicaid Services at 1-800-985-3059.

Disputing a Bill with a Patient Advocate's Help

Patient advocates are professionals who specialize in helping patients manage healthcare issues, including billing disputes. They can be extremely valuable when dealing with complex medical bills or when you don't have the time or energy to handle the dispute yourself.

How a Patient Advocate Can Help:

1. Bill review: They'll thoroughly examine your medical bills and insurance documents to identify errors, overcharges, or insurance coverage issues.
2. Insurance coordination: Advocates understand insurance policies and can determine if your insurer should have covered more of your expenses.
3. Provider negotiation: They can communicate directly with healthcare providers on your behalf, often securing significant reductions in bills.
4. Appeal denials: If your insurance has denied coverage, an advocate can help prepare and file appeals with all necessary documentation.
5. Paperwork management: They organize and track all your medical documentation and correspondence related to the dispute.
6. Financial assistance identification: Advocates can help determine if you qualify for hospital charity care programs, government assistance, or other financial aid.
7. Reduce your stress: Perhaps most importantly, they take the burden off your shoulders, allowing you to focus on your health rather than paperwork.

Solace advocates bring professional expertise to the table. They understand medical billing codes, insurance policies, and healthcare regulations – knowledge that most patients don't have. This expertise can make the difference between a successful dispute and a denial.

Disputing a medical bill requires attention to detail, persistence, and proper documentation. Remember that most medical billing disputes that patients initiate are resolved successfully, so it's worth the effort to challenge questionable charges.

Whether you choose to handle the dispute yourself or enlist the help of a patient advocate, knowing your rights and the proper steps to take can save you significant money and stress. Don't hesitate to speak up when you believe your medical bill contains errors or unfair charges – the healthcare system may be complicated, but with the right approach, you can successfully advocate for yourself.

Frequently Asked Questions About Disputing A Medical Bill

How long do I have to dispute a medical bill?

A: Typically, you have 30 days to send a formal dispute letter after receiving a bill. For insurance appeals, you generally have 60 to 120 days from the date of service to file a dispute, but timeframes vary by insurer and state.

What if my dispute is denied?

A: If your initial dispute is denied, you can escalate to a supervisor, request an external review, file a complaint with your state's insurance department, or consult a patient advocate or attorney.

Should I pay the bill while disputing it?

A: Consider paying the portion of the bill you agree with to avoid collections. For the disputed amount, ask the provider to put your account on hold while the dispute is resolved.
